1. 1. Analysis of combined response of railway bridge and track : A parametric finite element model of the bridge across Bryngeån

   University essay from KTH/Bro- och stålbyggnad

   Author : Moa Nolinder; [2023]
   Keywords : ;

   Abstract : When designing a railway bridge it is common to consider and designthe bridge structure and the track structure separately. However, theyare connected and that interaction generates a combined response and aforce transfer between them. READ MORE

3. 2. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats

   University essay from Luleå tekniska universitet/Byggkonstruktion och -produktion

   Author : Daniel Kostet; [2018]
   Keywords : ballasted track; bridge; elastic mat; expansion; finite element method FEM ; finite element analysis FEA ; floating slab mat; interaction; International union of railways UIC ; non-ballasted track; SOFiSTiK; ballasterat spår; ballastfritt spår; bro; dilatationsfogar; finita elementmetoden FEM ; finit elementanalys FEA ; fixerat spår; interaktion; Internationella järnvägsunionen UIC ; SOFiSTiK; vibrationer; vibrationsdämpande matta;

   Abstract : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. READ MORE

4. 3. Crosswind assessment of trains on different ground configurations

   University essay from KTH/Järnvägsteknik

   Author : Nachiyappan Venkatasalam; [2013]
   Keywords : Crosswind; ICE3; true flat ground TFG ; single track ballast and rail STBR ; atmospheric boundary layer ABL ; AeroTRAIN; CFD.;

   Abstract : Cross wind analysis is one of the important safety measures for rail vehicle certification. The objective of this study is to identify which vehicle certification ground setup, true flat ground (TFG) or single track ballast and rail (STBR) represents a more realistic ground setup with atmospheric boundary layer (ABL) wind inlet and also to represent an embankment scenario.

5. 4. The Influence of Under Sleeper Pads on Railway Track Dynamics

   University essay from Institutionen för ekonomisk och industriell utveckling

   Author : Stephen Witt; [2008]
   Keywords : railway rack; track stiffness; under sleeper pad; finite element model; hanging sleeper;

   Abstract : In this work the influence of Under Sleeper Pads on the dynamic forces on a railway track is investigated. A special interest is devoted to the effect of using Under Sleeper Pads in a railway track with changing vertical stiffness. The contact force between wheel and rail and the ballast contact forces are examined. READ MORE

6. 5. Environmental Performance of the Rail Transport System in a Life-Cycle Perspective : - The Importance of Service Life and Reuse in Sweden

   University essay from Institutionen för tema

   Author : Karin Swärd; [2006]
   Keywords : embodied energy; environmental performance; infrastructure; railway; reuse. service life;

   Abstract : The focus in environmental management has during the last decades in many cases shifted to include all the phases in a product’s (or a service’s) life – the life-cycle perspective. The transport system has a large environmental pressure on the environment. READ MORE
